Runs great, changed some fuses around now no spark and injectors not working. Engine turns over, every thing else works except fuse number 32 has no power to it. I look on diagram and one says 30 amp and other says 10 amp.

Hello, I am Danny.

The fuse #32 location is for the engine control-fuel injectors. It is a 10 amp fuse for gasoline engines and 15 amp for diesel engines. Just curious as to why you were switching fuses around? I can provide wiring diagrams if needed. I have attached a few tutorials to view. Hope this helps and feel free to ask questions if needed. Thanks for using 2CarPros.

My son was checking radio fuse and when I looked at the panel I noticed some empty spaces so I looked at the fuse panel card and some of the fuses were a different amp rating than what the card showed. I thought my son had messed them up and he was not around to ask. I may have caused my own problem, because when I went to start it I had no spark and no power to injectors, fuel pump is working and every thing else works. Number 32 fuse has no power it had a 30 amp fuse in. Car ran great and had no problems always started. I have been trying to find out what fuse 32 serves and locate any fuse links or what I may have burnt out. I had just replaced the thermostat and was letting the car sit a day before starting to see if any water leaks developed. Does fuse 32 go to a relay and what fuses control power to the coils? Wiring diagram would help. Thank you for any help in fixing this. David Shrewsbury

Hello again.

I have attached a wiring diagram for the Injector circuit. The wires run to the Motronic (ECM) Engine Control Module. It is located below left side of dash panel cover. Hope this helps and feel free to ask questions if needed. Thanks again for using 2CarPros.
